DEVICE FOR NAILING TIN'S ON BINDERS.

Specification of Letters Patent.

Patented July id, 1917.

AppIication filed October 12, 1916. Serial No. 125,221.

To all whom it may concern:

Be it known that I, MILO B. 1cm, a citizen of the United States, residing at Arcata, in the county of Humboldt and State of California,have invented a new and useful Device for Nailing Tins on Binders, of which the following is a specification.

By way of explanation it may be stated, as a matter within the knowledge of those skilled in the art, that shingles and like merchandise are secured in bundles by means of sticks applied to the opposed upper and lower faces of the bundles, the sticks being connected to each other, at their ends, by means of metal strips, the ends of which are overlapped upon the upper and lower faces of the sticks, and are secured thereto by nails.

The machine forming the subject matter of this application is adapted to be employed for nailing metal strips to both ends of a stick which is to constitute a part of a binder, for retaining a bundle of shingles or a similar package of merchandise.

The objects of the invention may be best understood by outlining in a general way, the various operations which are carried out in the device forming the subject matter of this application.

The machine forming the subject matter of this application includes a fixed platform, and a relatively movable platform, the relatively movable platform being adapted to be depressed at one end, below the corresponding end of the fixed platform, to define a shoulder. The sticks to which the strips are to be nailed are advanced by a conveyor, until one of the sticks abuts against the shoulder. Two ribbons of metal are advanced longitudinally, until their free ends overhang the stick which is in abutment with the shoulder above men tioned. The ends of these ribbons then are cut off to form strips extended longitudinally of the stick and located above the stick and at the ends thereof. During the operation which consists in cutting off the ends of the ribbons to form the strips, holes are punched in the free outer ends of the strips, beyond the ends of the stick, these holes being adapted to receive nails whereby the strips may be nailed to another stick, to form a complete binding. The inner ends of the metal strips which are cut off from the ribbons, are nailed by a suitable mccha nism to that strip which, having been advanced into the machine, is in abutment with the shoulder formed by the inner end of the fixed platform, when the inner end of the movable platform is depressed. Subsequently, the stick to which the strips have been nailed, is advanced, along with other sticks, out of the machine.

To provide a machine capable of carrying out the operations above mentioned, is, generally speaking, the object of the invent1on.

Further, the invention aims to improve the means for feeding the nails forwardly and downwardly, in front of the hammers whereby the nails are driven; to improve the mechanism for actuating the hammers; to provide novel means for cutting off the strips; to provide novel means for punching the strips at their ends and beyond the ends of the stick to which the strips are nailed; to provide novel means whereby the machine will operate properly upon sticks of difi'erent thicknesses; and to provide a novel mechanism for advancing the sticks through the machine.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

l/Vith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter describedand claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In carrying out the present invention there is provided a supporting structure including a main frame 1 and an auxiliary frame 2 fixed to and upstanding from the main frame 1, intermediate the ends of the latter. The auxiliary frame 2 preferably comprises vertical standards 3 connected by braces 4 with the sides of the main. frame 1, a top bar 5 connecting the standards 3, and lower bars 6 and 7 connecting the standards 8, the bars 6 and 7 serving not only to strengthen the auxiliary frame 2, but serving, as well,

. as guidesfor certain vertically reciprocating elements to be described hereinafter, Secured to the main frame 1 is a fixed horizontal platform 8 which may be upheld by supports 9 connecting opposed portions of the main frame 1, or in any other desired manner. The fixed platform 8 is provided along its edges with guides 10 cooperating with the sticks 11 of wood to the ends of which the metal strips hereinafter men tioned are nailed. The fixed platform 8 is further supplied with longitudinal grooves 12 receiving conveyer chains 32 which first advance the sticks 11 into the field of the nailing mechanism, and subsequently advance the sticks out of the field of the nailing mechanism, and out of the machine.

The invention comprises a vertically movable platform 14 provided on its under sur-' the platform 14 being yieldably supported,

and being adapted to be lifted, by mechanisms which will be. set forth hereinafter.

The movable platform 14 is provided along its side edges with guides 17 which coact with the ends of the sticks 11 while the sticks are being advanced into the field of the nailing mechanism. The movable platform 14 is provided with grooves 18 which, coacting with the grooves 12 of the fixed platform 8, receive the conveyer chains 32 whereby the sticks 11 are advanced first into the field of the nailing mechanism, and then out of the field of the nailing mechanism. As shown at 504 the grooves 12 are cut away so that when the platform 14 is depressed, the conveyer chains 32 are'not strained. Likewise as shown at 505-, the grooves 18 in the platform 14 are cut away to provide chain-clearance.

The numeral 19 designates a shaft extended transversely of the mainframe 1 and journaled therein. Fixed to'the shaft 19 are cams 20 coacting with rollers 21 on the lower end of vertically 'slidable rods 22 mounted to reciprocate in an offset 23 formed ona bar 24 the ends of which are connected to the main frame 1' or to some other fixed portion of the machine. Fixed to and depending from the bar 24, as shown. in Fig. 4, are U-shaped brackets 25 in which are mounted to reciprocate, vertically, pins 26 provided with shoulders 27 against which abut the upper ends of compression springs 28, the lower ends of the springs 28 abutting against the bottom portions of the brackets 25. The function of the springs 28' is to elevate the pins 26, and it will be observed that the shoulders or abutments 27, coacting with the bar 24, limit the upward movement of the pins; 26. The pins 26 cotent, the upward movement of the pin 26 and consequently the upward movement of the inner end of the platform 14 beinglimited by the engagementbetween the shoulders 27 on the pins and the under face of the bar .24. The rods 22, which are adapted to be raised by the cams 20 on the shaft 19, coact with the inner. end of the movable platform 14 to elevate the same. The spring elevated pins 26 constitute a yieldable support for the inner end of the movable platform 14.

Mounted for rotation in one end of the main frame 1 is a shaft 29. A similar shaft 30 is mounted in the other end of the main frame 1. The shafts 29 and 30' carry sprocket wheels 31 about which are trained the conveyer chains 32 hereinbefore a'lluded to. r r

The operation of the structure as thus far described is as'follows: I

The inner end of the movable platform 14 is supported yieldingly on the spring elevated pins'26, the inner end of the platform 14 being slightly below the inner end of the fixed platform 8, so that the inner end of the fixed platform 8 constitutes a shoulder against which the sticks 11, one after another, are advanced by the chains 32, as the sticks are moved by the chain, along the platform 14. At an appropriate time, the inner end of the movable platform 14 is elevated by the action of the cams 20 and the rods 22, so that the upper surface of the movable platform 14 is flush with the upper surface ofthe fixed platform 8. Then, the stick 11 to which the strip, hereinafter described, has been nailed, moves onto the fixed platform 8 and 01? the fixed platform 8, out of the machine. It has been pointed out hereinbefore that the spring elevated pins 26 may be depressed, and the utility of this particular operation will be taken up at a subsequent point in the specification. The foregoing comprises, in substance, the mechanism whereby the sticks 11 to the ends of which the strips are to be nailed, are moved through the machine. The next portion of the description relates to the means whereby the strips of metal which are nailed to the ends of the sticks 11, are fashioned from ribbons of metal which are fed forwardly, at an appropriate time.

The means for holding the ribbons of metal, for advancing the ribbons, and for cutting the ribbons crosswise to form the strips which are nailed onto the sticks 11, includes a shaft 33 extended transversely of the machine and journaled if desired in the braces 4. Fixed to the shaft 33 are reels 34 about which are wound ribbons of metal indicated at 35. Mounted on the side portions of the main frame 1 are bearings 36 in which is journaled a lower shaft 37 carrying rollers 38. Assembled with the bearings 36 are spring arms 39 in which is journaled a shaft 40. The shafts 37 and 40 are connected at one end by intermeshing pinions 507. The shaft 40 carries rollers 41 coacting with the rollers 38 on the shaft 37, the ribbons 35 of metal passing from the reels 34 between the rollers 41 and 38, these rollers being held in intimate contact with the ribbons 35 of metal by the action of the spring arms 39. As shown in Figs. 3 and 11, a ratchet wheel 42 is fixed to the shaft 40 and is engaged by a ratchet 43 pivoted to the upper end of a rod 44, the ratchet 43 being held in engagement with the ratchet wheel 42 by means of a spring 45 secured to the rod 44. The rod 44 moves vertically in a lug 46 on one of the standards 3 of the auxiliary frame 2, and in the offset 23 of the bar 24. At its lower end, the rod 44 carries a roller 47 engaged by a cam 48 which is secured to the shaft 19. A spring-constrained back-stop pawl 506 on the frame 3 engages the ratchet wheel 42.

It will now be understood that when the shaft 40 is rotated through the medium of the ratchet wheel 42, the ratchet 43, the cam 48 and the shaft 19, the ribbons 35 of metal will be advanced off the reels 34 by the action of the rollers 38 and 41, a step by step advancement being imparted to the ribbons 35, so that the same may be cut off crosswise, at their free ends, to form strips which are applied to the ends of the sticks 11 and are nailed thereto.

Referring to the means whereby the ribbons 39 are cut off crosswise at their free ends to form strips which are nailed to the sticks 11, it will be observed that fixed shears 49 are carried by the bar 24, the ends 50 of the fixed shears 49 overhanging the inner end of the movable platform 14, as indicated in Fig. 1, and as is evident from Fig. 4. The fixed shears 49 carry upstanding guides 51 between which the free ends of the ribbons 35 of metal move, as the ribbons are advanced off the reels 34. The numeral 52 designates a vertically reciprocating bar, the ends of which are slidably received in ways 53 mounted on the inner faces of the stand ards 3 of the auxiliary frame 2. At its ends, the bar 52 is supplied with shears 54 which, coacting with the fixed shears 49, cut the ribbons 35 at their free ends, crosswise, to fashion the strips which are nailed onto the sticks 11. Mounted for vertical movement beneath the fixed shears 49 are anvils The movable shears 54 are provided. in their lower edges with punches 56 adapted to cotiperate with openings 57 in the anvils 55, to form openings 136 in the strips which are cut from the ribbons 35, the openings being located in the free ends of the strips and beyond the ends of the stick. Secured to the vertically movable anvils are depending rods 58 slidably received in the bar 24. The lower ends of the rods 58 carry nuts 59. Strong compression springs 60 are interposed between the anvils 55 and the bar 24 and surround the rods 58. The function of the springs 60 is to hold the anvils 55 yieldingly elevated, upward movement on the anvils being limited by the nuts 59 which engage the lower surface of the bar 24.

The means for causing a vertical reciprocation of the bar 52 and consequently the movable shears 54 includes foot pieces 61 attached to the bar 52. Threaded at their lower ends, as shown at 62, into the foot pieces 61, or otherwise connected therewith adjustably, are rods 63 mounted to recipro cate vertically in the bars 6 and 7 which connect the standards 3 of the auxiliary frame 2. The rods 63 are threaded as shown at 64 into offset heads 65 carrying rollers 66 coiiperating with cams 67 secured to a shaft 68 journaled in the standards 3. Since the rods 63 are threaded as shown at 62 into the foot pieces 61, and because the rods are threaded as shown at 64 into the heads 65, the efiective length of the rods 63 may be adjusted, so that the rollers 66 will co6perate with the cams 67 under varying conditions of operation. At this point it may be noted incidentally that the shaft 68 is provided intermediate its ends with a crank 69, and carries cams 70 constructed, generally speaking, like the cams 67. The crank 69 and the cams 70, constitute parts of the nailing mechanism.

It is obvious that if the shaft 68 be rotated, the cams 67 will cause a reciprocation of the plungers or rods 63, the bar 52 and the shears 54L being caused to reciprocate vertically. Owing to this vertical reciprocation of the bar 52, the shears 51 at the ends of the bar are made to coiiperate with the fixed shears 49, the ends of the ribbons 35 being cut ofl to form the strips, which now may be designated by the reference character 133. The strips 133 by the operation above mentioned are punched, due to the coaction between the parts 56 and the openings'57, to form in the ends of the strips and beyond the ends of the stick 11,

' the holes 136.

The mechanism for holding and feeding the nails will now be described.

FiXed to and projecting from the standards 3 of the auxiliary frame 2 are arms 71 supporting a cross bar 72. Attached to the cross bar 72 is an upwardly and rearwardly inclined chute 73 which preferably includes a plurality of plates 74., spaced apart along their vertical edges, to form slots 7 5 through which slide the nails 13 1 whereby the ends of the strips 133 are attached to the strips 11. The numeral 76 designates a nail receptacle, which may be a boX, open at its top. The bottom of the nail receptacle 76 is indicated at 77 and preferably is composed of a plurality of strips, the edges of which are separated to form nail receiving slots 78 alined with the nail receiving slots of the chute 7 3. The constituent strips of the bottom 77 of the nail receptacle 76 are hingedas shown at 79 to the strips or plates 7 1 which make up the chute 73. A pitman 80 is pivoted to the nail receptacle 76 and is operatively connected with the crank 69 on the shaft 68, the construction being such that when the shaft 68 is rotated, a vertical shaking motion will be imparted to the nail receptacle 76, so that the nails therein will drop down into the slots 78 in the bottom 77 of the nail receptacle and traverse the slots 75 of the chute 7 3, the heads of the nails engaging the bottom 77 of the nail receptacle and the plates 74 of the chute 73, upon opposite sides of the slots, so that the nails cannot drop out of the machine.

The numeral 82 indicates a support located below the plates 741 of the chute 73 adjacent the lower ends of the said plates. The support 82, which is shown best in Fig. 6, includes a rear flange 83 attached as shown at 81 to the plates 74 of the chute 73. The

support 82 includes, further, a depending body 84 and a substantially horizontal base 85. In the rear flange 83 are fashioned slots 86 alined with the slots 75 in the chute 73. In the depending body portion 8430f the support 82 are slots 87 which are alined with the slots 86, to permit the passage of the nails 134. By means of securing elements 88, an angle bracket 89 is attached to the body 84: of thesupport 82.' The vertical flange of the angle bracket 89 is shown at 90, and the horizontal flange thereof appears at 91. In the vertical flange 90 of the angle bracket are fashioned slots 92, alined with the slots 87 in the body 81 of the support 82 and adapted to permit the passage of the nails 131. Tubes 93 are secured to the base of the support 82 and" to the horizontal flange 91 of the angle bracket 89. The numeral 91 indicates a brace extended transversely of the chute 73 and secured thereto, the brace 941 being upwardly arched, as shown at 95, above the slots 7 5, so that the heads of the nails 13% will not be engaged by the brace as the nails slide downwardly in the slots 75.

The invention comprises a slide whereby the nails are segregated and are deposited one at a'time in the tubes 93. The slide is indicated by the reference character 96 and is in defining a shoulder 100. The vertical flange 98 is mounted to reciprocate on the shoulder 100 and is held in place by an angle member 101 held on the base 85 ofthe support 82 by securing elements 102. The upright flange of the angle member 101 is provided with slots 103 which, coiiperating with the openings shown at 99 in the tubes 93 permit the nails to enter the tubes. The vertical flange 98 of the slide 96 is provided with openings 101 coiiperating with the openings 99 in the tubes 93. The openings 10 1 communicate with slots 105 formed in the horizontal flange 97 of the slide 96. The slots 105 define tongues 108 in the flange 97 and in the flange 98 of the slide 96 where these elements join. '(See Fig; 7.) Stops 106 are secured adjustably by bolts 107 to the flange 97 of the slide 96, the construction being such, as indicated in Fig. 6,

been described hereinbefore in connection with the stop 106. The plate 110 has an upstanding curved lip 135, conforming to the opening 109 in the flange 97 The operation of the structure last above described is as follows:

When the nail receptacle 76 is reciprocated in a vertical direction by the action of the pitman 80 and the crank 69 on the shaft 68, the nails 13 1 drop into the slots 7 8 in the bottom of the nail receptacle 76 and traverse these slots, and the slots 7 5 in the chute 73, as well. The nails 134 being supported by their heads, pass through the slots 86 in the supports 82 and enter the openings 104: in the slide 96, the nails abutting against the stop members 106, in a man ner which will be clearly obvious from Figs. 6 and 7, the nails being upheld, within the contour of the tubes 93, because the heads of the nails engage the stop members 106. If the slide 96 be moved to the left, referring to Fig. 7 it is obvious that the tongue 108 will segregate one nail from the other nails in the slots 7 5 and, if the slide 96 be moved to the left a sufficient distance, the head of the nail ultimately will enter Within the contour of the lip 135 on the plate 110, the nail then dropping downwardly into the tube 93, through the opening 109.

The means for moving the slide 96 positively to the left, to segregate a nail and to permit the nail to pass through the open ing 109 and into the tube 93 includes a fieXible element 114 passed about a pulley' 115 supported on any accessible portion of the machine, a suitable means, hereinafter described, being provided for exerting a pull 011 the flexible element. The slide 96 is returned by a retractile spring 112, secured to the slide and to any appropriate part of the machine.

Telescoped on to the tubes 93, as shown at 116, are tubes 117 which are connected with the shear bar 52 and open into passages 52 in the shear bar. The shear bar 52 carries casings 500 in which are located grips denoted generally by the numeral 118. The grips comprise cooperating jaws 119 and 120, mounted to move toward and away from each other on a rod 501 mounted on cars 502 connected with the shear bar 52. Compression springs 503 are mounted on the rod 501 and engage the ears 502 and the jaws 119 and 120. The bores of the grips 118 are tapered toward their lower ends to form shoulders 521 which are adapted to engage the heads of the nails 134 thereby to prevent the nails from moving downwardly beyond a predetermined point.

It will now be obvious that the nails traverse the tubes 93, the passages 52 in the shear bar 52, and the tubes 117, the nails passing into the bores of the grips 118, and

being sustained and upheld, releasably, by the jaws 119 and 121, as shown best in Fig. 9.

A means is provided for driving the nails positively downwardly, out of engagement with the jaws 119 and 121 of the grips 118, this means comprising hammers 123 in the form of plungers or rods, mounted to reciprocate in the bores 52, as will be understood best from Fig. 9. The hammers 123 are connected as shown at 124 with plungers 125 mounted to reciprocate in the bars 6 and 7 which connect the standards 3 of the auxiliary frame 2. The upper ends of the plungers 125* are adjustably secured, by threading or otherwise, as indicated at 126, to offset heads 127 having rollers 128 coacting with the cams 70 on the shaft 68.

When the shaft 68 is rotated, the cams 7 0 will reciprocate the plungers 125 and cause the hammers 123 to drive the nails downwardly out of the grips 118, through the strips 133, the strips 133 thus being secured to the ends of the sticks 11.

The nails are liberated just as the 11ammers or plungers'123 are near the lower end of their strokes. The nails remain in position until the hammers are withdrawn far enough to allow the nails to enter the grip 118.

The driving trains of the machine include a pulley 129 or the like on the end of the shaft 68, a sprocket chain 130 connecting the shaft 68 with the shaft 30, and a sprocket chain 131 connecting the shaft 30 with the shaft 19. It will be seen that when the shaft 68 is rotated, thereby reciprocating the shear bar 52 and the hammers 123, the shaft 30 will be rotated by the sprocket chain 130, thereby causing the conveyer chains 32 to move with respect to the tables 14. and 8. By means of the sprocket chain 131, motion will be transmitted from the shaft 30 to the shaft 19, and when the shaft 19 is rotated, motion will be transmitted by the mechanism shown in Fig. 11, and hereinbefore described, to the means, comprising the shafts 40 and 37, for advancing the ribbons 35. Further, as has been pointed out hereinbefore, when the shaft 19 is rotated, the means for actuating the movable platform 14, comprising the rods 22, will be actuated by the cams 20.

As shown at 132, the flexible element 114- which actuates the slide 96 is connected with one of the plungers 125, so that when the plungers are moved downwardly, the flexible element will be drawn upon, thereby moving the slide 96 endwise, and causing the slide to segregate a nail and to permit the dropping thereof.

Since the operation of the structure has been dealt with hereinbefore step by step, a somewhat abbreviated rsum will make manifest the way in which the device exercises its functions.

It may be noted at this point that the chains 32 move continuously during the nailing process.

Let it be supposed that the inner end of the movable platform 14, being yieldably supported by the spring elevated pins 26, lies slightly below the inner end of the fixed platform 8 to form a transverse shoulder. Then the sticks 11 are advanced by the chains 32 until one stick 11 abuts against the shoulder above mentioned, that is, against the inner end of the fixed platform 8. The ribbons 35 in the mean time have been advanced by the rollers 38 and 41 until the free ends of the ribbons lie above the ends of the stick 11 which is in abutment with the inner end of the platform 8. The movable shears 54 descend along with the bar 52 and cut off the ends of the ribbons 35 to form a pair of strips 133 located above the ends of the stick 11 which is in abutment with the inner end of the fixed platform 8. The hammers 123 now descend, dislodging the nails 134 from the grips 118 and driving the nails through the strips 133 into the ends of the stick 11 which is in abutment with the inner end of the fixed platform 8. Then the nailing has been completed, the cams 20 act on the rods 22 and raise the inner end of the movable platform 14, so that the inner end of the movable platform 14 is flush withthe inner end of the fixed platform 8. The inner end of the movable platform 14 remains flush with the inner end of fixed platform 8 for a short interval, say until the stick 11 to which the strips 133 have been nailed has moved a quarter of an inch or so to the left, referring to Fig. 2, beyond the inner edge of the platform 8, and then, because the cams 20 have been rotated sufliciently, the inner end of the movable platform 14 moves downwardly below the inner end of the fixed platform 8, so that the inner end of the platform 8 defines a shoulder, as aforesaid, adapted to engage the next stick 11 as the same is advanced by the chains 32. The sticks 11 to which the punches 56 coiiperating with the openings 57 fashion the holes 136 in the free ends of the strips 133 which are nailed to the stick 11. It is to be observed that the anvils 55,

being pushed upwardly by the springs 60, hold the strips 133 while the same are being severed by the shears 54 from the ribbons 35, and also hold the strips 133 while the same are being nailed to the ends of the stick 11. When the shears 54 movedownwardly, they press downwardly that strip which is immediately beneath the shears, down hard onto the stickll the springs 28 being compressed, and the inner end of the platform 14 moving downwardly. This movement is of importance, when, as is occasionally the case, the sticks 11 are not of the same thickness, and it permits the nailing hammers 123 to have the same stroke, always, even though the stick 11 which is being nailed is somewhat thicker than the remaining sticks. p

The operation of the nailing mechanism has been dealt with at length hercinbefore, but it will be understood that when the shaft 68 is rotated, the pitman 8O reciprocates the nail receptacle 76 vertically, and the nailsin the receptacle 7 6 are caused to traverse the slots 'of the chute 73. The nails are admitted one at a time into the tubes 93 by the action of the slide 96 and are-forced downwardly out of the grips 11S and into the strips 133 and the sticks 11 by the action of the hammers 123.

Because the fixed shears'49 overhang the movable platform 14 as shown. at 50, the

severed strips 133 will overlap the ends of the stick 11 suficiently sothat those endsof the strips 133 which are adjacent thelongitudinal center of the machine may be secured by the nails to the stick.

- It is obvious that each of the strips 133' may be secured to the stick 11 by more than one nail, and that as many holes may be punched in the strips as may be necessary.

Having thus described the invention, what is claimed is 1.111 a device of the class described,a

frame; stick-feeding means carried thereby; means for feeding metal ribbons transversely of the stick; movable means on the frame for severing the ribbons to form strips; and means for nailing one strip to each end of the stick.
